I'm planning plumbing to an outbuilding.
When I splice in to the water line, I'm thinking I should insert a shutoff valve with a weep hole ("stop and waste"). Then, if I leave for the winter, I can drain the line to protect from freezing.
Is this sensible?
The water line is 1" HDPE. Are there stop-and-waste valves with barbs for poly line?
Or should I use a pair of regular valves - one for supply, one for draining the line?
EDIT: I should note that our specified frost depth is only 12". The valve won't be very farbelow grade. Of course, maybe such a mild climate means this is overkill.
